“…By measuring and calculating the air consumption ratio and relative ratio, trapping efficiency can be calculated. Figure 5 shows the flow of working substances in a cylinder and from the cylinder according to the [10,11]. Figure 5 is a modified and significantly improved version of the figures shown in the literature [11], particularly in relation to [8][9][10].…”

Abstract:The aim of this research was to investigate the mass, substance and energy flow through two-stroke low speed Diesel engines. For this reason, a zero-dimensional model of the combustion in the engine was developed with a calculated amount and composition of exhaust gases. Due to the large amount of oxygen in the exhaust gases, a ratio of real air consumption and stoichiometric amount of air required for combustion of injected fuel was set. The calculated ratio showed that the engine consumed four times more air than needed for combustion in AFR stoich . In this work, this was called the Air Consumption Factor or Ratio, and has not previously been mentioned in scientific literature. The air consumption ratio is defined as a factor of dry or humid air. To be more comprehensive, a modified diagram of the composition of the flow in and out of a two-stroke fuel injection engine and the cylinder was made.
